35mm black and white film camerais an orthochromatic black and white negative film optimized for technical, scientific, and half-tone work, as well as creative and pictorial applications. Characterized by extremely high sharpness and resolving power, this unique film also features an impressively fine grain structure and is also well-suited to reversal processing for black and white transparencies. Ortho 25 has a nominal sensitivity of ISO 25/15° and a high-sensitivity reserve of two stops for greater flexibility when shooting. Its spectral sensitivity ranges from 380-610nm and is suitable for photographing in either daylight or tungsten-lit conditions. The film's polyester base has been tested to an LE-500 (life expectancy 500 years) archival rating and also features anti-curling and anti-static coatings, as well as a special coating to promote smooth film transportation within the camera. Additionally, this clear base is particularly well-suited to scanning applications.

Q: 1. What's the expiry date if i were to get now?

A: The following item has a expiry date of march 2024. Recorded on 3/18/22

Q: 2. Can I develop this film using C41 developer? Thanks

A: No way... This is a standard B&W film. Best developer to use is Rodinol 1/32 at 8.5 minutes. This is definitely NOT a C-41 film.

Q: 3. How long does this film need to be developed in the darkroom?

A: My friend this film behaves pretty much like any other B&W film, and personal preferences upon what final results you may be looking for will determine dark room procedures. Delta 100 has a great and well balanced contrast range. If you are looking normal B&W results, and with standard developers at normal 72-75 degrees ambient temp, I will suggest 10 to 12 minutes, agitating (more like soft shaking..not a bartender kind) 10 seconds at each 2 minutes interval then leave the tank upside down the next 2 minutes and agitate again when you put it up (two min upside down, two min up) and repeat until the 10 to 12 minutes are gone. So, let's say if you did use 10 minutes procedure, you will agitate 5 times total with a 50 seconds (10 sec x 5 times) at each inversion. Remember that more agitation, the more contrast you will get, and the more time means pushing the exposure. I hope this may work for you, let me know.!!!

Q: 4. Is this one roll of 100' or are there multiple rolls that add up to 100'?

A: Its one continuous roll of film 100 feet long, you can cut it to any length you need for your cassettes.

Q: 5. Is this film compatible with an Olympus Infinity Stylus camera or just the Holga?

A: You can use this film with any 35mm camera.

Q: 6. Does this fit in a normal camera? Because 100' seems like a lot.

A: this is bulk film meant to be cut and loaded into film holders such as Kalt 35mm Cassette For Bulk Film: https://bhpho.to/2pPsUnw

Q: 7. Is this film 36 exposure?

A: The Vello Wireless ShutterBoss Timer Remote (Sony Alpha Connection) is compatible with the A55, yes. This film is not 36 exposures, no. It is a 100 roll of film that would need to be loaded into empty film cassettes before it could be used. The following would be a 36 exposure ISO 100 roll of Ilford Delta:Ilford Delta-100 Professional 135-36 Black & White Negative (Print) Film (ISO-100) (B&H # ILD10036).

Q: 8. Does this film work in normal lighting or extreme lighting?

A: As a 50 iso ( slower, less sensitive to light) film it requires a fair amount of light. If you're used to shooting 400 speed film like HP5+, you'll also likely notice this film has more contrast.

Q: 9. I bought the Lomographic sprocket rocket (hp400) and would like to know if anyone knows how long the developed photo is. I've had a panoramic camera in the past and the developed photo was 12 long. 2. I also have a Nikon N90s which uses 4AA batteries, along with 4 AA's in the flash. Any strong recommendations on type of battery? I'm finding Duracell are weaker and energizer last longer. So, any suggestions?

A: In regard to the Sprocket Rocket: The size of the print just depends on what you request. The image on the negative is about twice the length of a standard 35mm frame. I've printed images from the Sprocket Rocket on 8x10 paper. You can really print them at almost any size.

Q: 10. Can I use this for my argus super 75 camera? A blog said j could and I'd like to make sure.

A: Hello! I'm not sure if this will help you. But I have a Holga, and I think the principle will be similar. I've only shot 120 film in my Holga though. I think that is the ideal film format for your Argus Super 75. If you want to run 35mm film though instead, because it's narrower, you should put some sort of buffer on the outer edges, so that the film tracks straight. Otherwise it might track up and down the wider spool, and photos might be less predictable? As far as what that buffer is, you may need to be creative. You could try stacking some rubber washers, you'll likely need to cut one end of the circle to get them around the core of spools. I hope that helps! I'm sorry, I'm no expert on your camera, but I think this should be pretty accurate! Good luck!
